REGISTR-CONTROLLING SYSTEM.

Application filedr September 21, 1923. Serial No. 663,976.

This application is a continuation in part ot the application oflinndell an'd Clark, Serial No. 301,891, filed June 5, 1919.

This invention relates to a telephone`iexchange system and moreparticularly to systems in which registrations must be set up andtransferred.

It is an object of this invention to provide an improved registercontrolling system.

1n machine switching systems, the speed with which pulses aretransmitted is alarge factor in the control ot the machine switchingapparatus `for making service connections I'rom one subscriber toanother. The setting of a large'nuinber of registers at one time throughan impulse generating device makes it possible to reduce materially thenumber oi combinations of apparatus and switches necessary to providepaths for the large number of telephone calls transmitted through atelephone exchange' of this type.

The utility of a rotary impulsor switch for setting a plurality ofregisters is shown in the patent application oli A. E. Lundell and E. H.Clark Serial No. 654,106, filed July 27, 1923 and in the Patent No.1,501,676 to A. E. Lund-ell and J. J. lVynne issued July 15, i924..

A v'feature of this invention is in the use an inipulse generatingdevice for simultancously setting a plurality of registers.

A tnrther feature of this invention is in the particular arramgjcmentoi'i the relays constituting the register. v

These and other features of the invention will be apparent from thefollowing description' taken in connection with the accompanyingdrawings.

l'hile the invention has been disclosed as particularly adapted torsetting registers ot a. machine switching system, it will be apparent,however, from the -following descripm tion that the invention has awiderutility and that by slight modification, it could be adapted for usewith other types 4or. apparatus in which speed of setting registers is adesired Object.

Fig. 1 illustrates the' apparatus and circuits or controlling thesetting of register relays shown in Fig. 2. Fig. 2 illustrates two setslof register relays and associated lamps. Fig. 3 illustrates the order inwhich the dra-wings should be arranged.

Descriptc'oa of apparatus.

The rotary impulsor switch 510 is preferably of cylindrical `form but tomake the disclosure more readily understood, the cylinderv has beendeveloped int-o a plane rectangular surface. The cylindrical iorm mayb-e of a type similar toa rotary commutator with numerous segments. 1tmayy loe-constantly General desmiz'ptzoa.

The circuit paths over which register -relays 607 to 610 operateare.carried through the contacts of relay 231 to brushes 526to 529` of theimpulsor switch. Upon each revolution of the impulser switclnground issuccessively connected tOv brushes 526 to 529 through segments 537 to5110. Ttfis apparent that it relay 231 is operated when oneot brushes526 to 529 is engaged `with one oty segments 537to 5410, a registerrelay is operated. Therefore, any of the register relays 607 to 610 maybe operated during one revolution of the impulsor switch by connectingthe circuit path over which relay 231Operates to a brush brought intoengagementwith segments .in a horizontal-'plane withseg` ments 537 to540. Brush 513 is brought into engagemei'it with segments 531, 532 and533. `With the 'operating path for relay 231 connected to'brush 513,relay 231 is operated, when segment 537 is engaged with brush 526, whensegment 538 is engaged with brush 527 and when segment 540 is engagedwith brush 529. Therefore, three ot' the register relays are operatedto: light a particular lamp. The circuit path to light each lampisestablished by the 1 actuated-or non-actu`- iii ated position ofcertain ones of the register relays.

A second set of register relays 611 to 614 are shown and are operableunder thecon- Y pulsor.

Vbrushes 440 and 443with the contacts connccted with conductors 441 and445, respectively. VUpon the positioning of switches 300 andk 400, letit be assumed that relay 602 is actuated to establish a circuit path forrelays 226 and 227 The detailed operation of switches 300 and 400 andrelay 602, with their associated circuits, is described in detail in thepatent application of Lundell-y Clark, Serial No. 654,106, led July 27,1923.

AV circuit is now established to operate relays 226 and 227 which may betraced from grounded battery through the windings of these relays inmultiple, contact andarmaf ture of" relay 602, right continuity contactsoflrelay226, resistance 290, brush 511 to ground through segment 512 ofrotary impulsor switch 510.k The operation of relay 226 establishes alocking circuit for itself Vand `for relay 227 which may be traced fromgrounded battery through the windings of these relays in multiple,contact oi' relay 602, right contact and armature of relay 226 to groundthrough key 291. The operation of relay'226 further establishesactuatingcircuits for relays 229 and 231. Y

As described ,in the aforementioned patent application of LundellClarkthe 'appa-V ratus of Fig. 2 and the apparatus of Fig. 1

with the exception of switches-300 and 400 and the rotary impulsorswitch 510 is all located in the operators position Yof the switchboard.Conductors such as 340 and 343 connect the armatures oi relays such as226 in the various operators positions with the various contacts ofswitch 300. The brushes 341 and 344 are those rotated for associationwith conductors extending to a particular operators position. y Thecircuit for actuating relay 229 lmay Y be traced from grounded batterythrough its winding, conductor 253, left inner contact and armature ot'relay 226, conductor 343, brushf344 and its associated contact, brush443, andl its associated contact, conductor 445, brush 514 togroundsuccessively through commutator segments 535 and 536 of theconstantly rotating impulsor switch 510. The circuit established toactuate relay 231 may be traced from grounded battery through itswinding, conductor 254, left outerV contact and armature of relay 226,'conductor 340, .brush 341 and its associated contact, brush -440`and itsVassociated contact, conductor 513 to ground* successively 441, brush yc through the segments 531, 532 and 533 of the constantly rotatingimpulsor switch 510.

As broughtout in the general description,

Vupon each revolution of the impulsor switch,

ground is successively connected from segments 537, 538, V539 and 540 toimpulsor switch brushes 526,527, 528, and 529. It is now apparent thatduring the time the actuating circuit is `established for relay` 229from ground through segment 535, also during the time that a circuit isestablished for relay 231 to ground through .segment 531,

acircuit is established from `ground through Vcommutator segment 537,brush` 526, .con-

ductor 232 over a divided path through theV contacts and armatureswofrelays 229 and 231.4 The path through the contacts of relay 231 may betraced from conductor 232, left outer armature and contact of relay 231,conductor 245, left winding of relay 607, to grounded battery, operatingrelay 607. The circuit path through thecontacts of relay 229 may hetracedtroml conductor 232,

kmi

through the lett outer armature and contact ofi-clay 229, conductor 250to grounded battery through the left winding ont relay 611, operatingrelay 4611. Relays 607 and 611 in operating establish locking Vcircuitsfor .themselves from grounded battery through their right j windings,right inner contacts and armatures to ground through contacts of lkey291.

Upon further rotation of impulsor switch 510, circuits are againestablished to operate relays229 and 231 through impulsor switchsegments 536 and 532 respectively. During the time that these circuitsare' established a circuit is established from ground throughcominutator segment 538, brush 527, conlll) 'ductor 233 over ar dividedpath through the contacts o'f relays 229 and231. The circuit through thecontacts of relay 231 may be traced from conductor` 233, left innerarmature and contact ot relay 231, conductorv244 .to grounded batterythrough the lett wind-V ing of relay 609. Thecircuit through thecontacts of relay 229 may be traced from conductor233, left innerarmature and contact of relay 229 conductor 247 to grounded batterythrough the left winding of relay 613. Relays 609 and 613 arefactuatedand establish locking circuits for themselves from grounded batterythrough their right windings, right inner contacts and armatures toground through the contacts of key 29.A

of relay 231, conductor 2412 Vto grounded battery through the leftkwinding of relay 60S. Relay 608 is actuated and establishes a lockingcircuit foritself from grounded battery through its right winding, rightinner contact and armature to ground through the contacts of key 291.

Upon further rotation of impulsor switch 510, a circuit is establishedfor operating relay 206. 'This circuit may be traced from groundedbattery throughthe left winding'l of relay 206, left Contact andarmature oi relay 227, brush 530 to ground through iinpul'sor switchsegment 541. Relay 206 in operating, establishes a locking circuit toritself and an operating circuit for relay 228. vThe locking circuit maybe trace-d from grounded battery through the right winding and rightinner contacts of relay 206 to ground through the contacts `ofy key 291.The operating circuit for relay 228` is ob Vious and need not be traced.The remaining circuits established by the operation of relays 206 and228 connect ground and grounded battery to the Various lamp circuits.

The foregoing describes the registerl relay groups which are arranged ona coordinate basis. The relays forming the vertical ort inate groupinghave not been placed on the drawing on a vertical line with each other.This is thought not to bematerial for an understanding of the relaygrouping on a coordinate basis. The register relays ol' Fig. 2 arearranged in two groups. Relays 607 to 610 inclusive form one group andrelays 611 to A614 form another group. Selection is accomplished on acoordinate basis. Selection of a group-may betermed selection withrespect to one ordinate and selection within the group may be termedselection with respect to another ordinate. This corresponds totheterminology which is used in connection with `point types'tep-by-step switches in which the switch terminals are frequentlyspoken of as being arranged on a coordinate basis. In the case of theswitch, the selection of a level or group is a selection with respect'to one ordinate and selection within the chosen group is a Aselectionwith respect to a secondary ordinate.

, Selection within the group in thefpresent case is accomplished bymeans of brushes In this horizontal vlight lamp 6j of register A.

526 to 529inclusi`ve and selectionof a7 group is determined by the'action of any'jof the brushes other than the pick-up brushes 'whenwired so as to control relays 231`and`229 which maybe .operated eitherindependently or simultaneously. As a result,'corresponds ing' relays inboth ncously energized'. A

lt will be remembered that relays 607,608 and 609fot register A wereoperated and locked during one revolution ot impulsor switch 510. Acircuit is now established to This circuit may groups may be simultabetracedlirom grounded battery through the .y right outer armature andcontacty of relay 206, conductor 2st-0, lett outer armature and contactoil' relay 608, lamp 6, left inner armature andcontact ol.V relay`607,vleft contact and armature ot relay 609,v right inner contact andarmature oi' relay`608 to ground through the contacts of key 291.

llt will be remembered that relays 611 and 613 or register B wereoperated and locked during the same revolution ot" the impulsor switchthat operated the relays ot' register A. A circuit is now established tolight lamp '7 of registerB.V This circuit may be traced from groundedbattery through the lett middle armature and contact of relay 228,conductor 256, lett outer normal armature and contact of relay 612,leftarma-k ture and contact of relay 613, left inner armature andcontact ol relay 611,'lamp 7, right inner normal contact and armature ofrelay 612', to ground through thel contacts of key 291. v

Since lamp 6 of register A is lighted and lamp of register B is lighted,number 67 is shown to indicate that a trunk or line of that numberhasbeen selected by switch 400. fter the number has been indicated bythe lighting ot' the lamp in registers A and B. an operator may actuatekey 291 to release all of the relays that are held in a lockedYposition. This includes relay 602, in addition to the; register' andcontrol relays. Register relays A and B may now be used for anotherregistration upon i the dillerent trunk or line. i

Impulsor switch 510 is used as a common selection of a of switch 400 areassociated. Several' types obtainablelvvith' the registers A -andB andwith the` rotary impulsing switch 510` for indicating the various digitsof trunk desshown connected to brush542 of the rotary impulsing switch.'A switch of the type shown for switch 400 has a large number ofterminals associated With each brush and the conductors that connect thebrushes of the rotary impulsing switch to the terminals associatedl withbrushes 440 and 443 may be arranged in any desired combination toopcrate the relays of register A or B iii any of. the desiredcombinations shown in the tabulation. An example. may be assumed for ylighting the zero lamp or register A and the No. 3 lamp of register B.From the tabulation, `it is found that a conductor the saine asconductor 441 is `connected from one of the switch terminals associatedwith brush .440 to rotary impulsor brush 529. When a conductor is` soconnected and brush 440 is resting on the terminal connected to thisconductor, lrelay 608 is operated upon a rotation of the impulsorswitcli'and lamp 0 is tlius lighted. To light lamp 3 of register B, itis. found from the tabulation that aconductor the same as conductor 445is rconnected to one of the switch terminals associated with brush 443and is also connected to the rotary impulsor brush 526. With brush 443resting upon `a terminal so connected relay 611 is operated upon arotation ofthe impulsor switch andV lamp 3 is thus lighted.
